H EATI NG-STOVE.

SPECIFICATICN forming part of Letters Patent N0. 700,386, dated May 17, 1904.

Application filed October 22, 1902. Serial No. 128,336. (No model.)

To all whom it #may concern:

Be itknown that I, THEoDoRE A. DoUGH'rY, a citizen of the United States of America, residing at Elkhorn, in the county of Walworth and State of Visconsin, have invented certain new and useful Improvements in Heating- Stoves, of which the following is a specilication.

My invention relates to certain new and useful improvements in heating-stoves; and its object is to produce a fire-pot which shall protect the casing oi' the stove in whichit is used from the deleterious influence of the tire and still permit free radiation of heat through the casing.

To this and certain minor ends my invention consists in certain novel features ot' construction, which are illustrated in the accompanying drawings and described in the speciiication.

In the aforesaid drawings, Figure 1 is a perspective ot' my improved fire-pot, and Fig. 2 is a front view or' the stove, a portion oi' the wall of the stove being broken away in a central vertical plane and a portion of the repot being broken away to show the construction and relations of the parts.

Referring to the drawings, A is the wall of a stove, which may be of any form, but which is here indicated as being cylindrical.

The stove is supported upon a suitable base or legs A and is provided with a top A2 and a stovepipe A3, opening into the top.

The particular construction of the stove is entirely immaterial, and it is to be understood that it can be varied as desired.

/Vithin the lower portion of the stove is shown my improved fire-pot, the constluction of which is best seen in Fig. l. Twol horizontal annular ribs C form the top and bottom of this device, and between these ribs run a plurality of vertical sections d, between which sections are vertical slots c. Upon the back ot each of the sections l is a vertical rib a, which projects outward from the section a distance equal to the amount which the ribs C project outward therefrom, and from these central ribs a to the slots c extend downwardly-inclined diagonal ribs of equal width with the ribs a. /Vhen inplace in the stove,

the ribs C Clie in contact with the inner face thereof, as do the ribs a b. By this arrange ment it will be seen a space is provided outside the {ire-pot and between it and the wall ot' the stove.

It is to be understood that while I have shown and described the lire-potas being cast in one piece, and while this is the preferred form ot' construction, still the same structure can be made of a number of separate sections secured together by bolts, screws, or in any other obvious way.

The operation of this device will now be explained. The tire is built inside the lire-pot in the ordinary way, any combustible substancebeing used for fuel, and the burning vapor passes up through the center of the stove and strikes the tire-pot. A certain amount of heat is ot' course conducted through the sections d and heats the gas between the lire-pot and the wall of the stove, which in turn heats the wall of the stove, and so the room. A much greater amount oi' heat, however, passes directly through the slots c and heats the wall of the stove directly; but no great body or flame can pass through these slots, and consequently the wall oi' the stove is entirely protected from the oxidizing' action of the iiame. In spite of this fact, however, a very large proportion of the heat is radiated.

The diagonal ribs catch any ashes which may work inside the {ire-pot, either over the top or through the slots c, and cause them to fall away from the central portion oi' the sections (Z and toward the slots c. Apertures e are provided at the bottom of the slots c in the lower flange C, through which the ashes may fall into the ash-pit at the bottom oi the stove. In this way the space between the lining and the wall ot `the stove is prevented from filling up. These apertures e have a further advantage in that fresh air rises from the space below the tire-pot through them, passes through the slots in the sides ot' the iire-pot, and reaches the entire body of burning fuel.

I realize that considerable variations are possible in the details ot' this construction withoutdeparting from the spirit ot the in- IOO vention, and I therefore do not intend to limit myself to the specific form herein shown and describedv except as pointed out in the Claims.

I Claim as new and desire to secure by Letters Patent- 1. The combination with the wall of a stove, of a lining therein and Substantially parallel thereto, composed of a plurality of sections separated by vertical slots, each of said seotions having upon its outer side diagonallydisposed ribs adapted to deflect foreign material into the line of the slots.

2. The combination with the wall of a stove, of a plurality of lining-Sections secured together by suitable flanges at the top and bottorn, said sections being separated by vertical slots, and each of said sections having upon its back a vertical rib and oppositely-inclined diagonally-disposed ribs running from said central rib downward toward said slots, whereby foreign material is deflected to the line of said slots.

3. The combination with the Wall ofa stove,

of a plurality of lining-sections Secured together by suitable liangesatzthe'top and bottom, Said sections being separated by vertical slots, and each of said sections having upon its back a vertical rib and oppositely-inolined diagonally-disposed ribs running from said central rib downward toward said slots, whereby foreign material is deflected to the line of said slots, the lower flange being eut away to permit such material to fall into the ash-pit.

4. The Combination with the wall of a stove, of a lining therein having asui-tale flange at the bottom, said flange being eut away at intervals, the lining having a plurality of perforations opening into the space between the lining and the walls of the stove and having upon its outer side a series of diagonally-disposed ribs adapted to guide foreign material into the spaces in the lower flange.
